2003 Buick Century Owner ManualM

Front Seats
Manual Seats
{CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle
is moving. The sudden movement could startle
and confuse you, or make you push a pedal
when you don't want to. Adjust the driver's
seat only when the vehicle is not moving.
Lift the bar located under the front of the passenger
seat to unlock the seat. Slide the seat to where you want
it and release the bar. Try to move the seat to be
sure it is locked into place.
1-2

Six-Way Power Seats
The control for the driver's
side power seat is located
on the outboard side of
the seat cushion. Your
vehicle may be equipped
with a passenger's
side power seat. That
control is located on the
outboard side of the
passenger seat cushion.
·To move the seat forward or rearward, push the
control forward or rearward.
·To raise or lower the entire seat, push the control
up or down.
·To raise or lower the front of the seat, push the
front of the control up or down.
·To raise or lower the rear of the seat, push the rear
of the control up or down.
Reclining Seatbacks
Lift the lever located on the outboard side of the seat to
release the seatback, then move the seatback to
where you want it. Release the lever to lock the
seatback in place. Pull up on the lever without pushing
on the seatback and the seatback will move forward.
1-3

Rear Seats
Split Folding Rear Seat
If the vehicle has a split folding seat, you can gain
access to the interior of the vehicle through the trunk.
To do this, pull forward on
the seat tab, located on
the side of the rear seat, to
move the rear seatback
down.To return the seatback to its original position, push it
back up, making sure the seat latch locks it in place.

Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see ªSeatsº in the Index.3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt isn't long enough, see
Safety Belt
Extender on page 1-29.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.

5. To make the lap part tight, pull down on the buckle
end of the belt as you pull up on the shoulder belt.The lap part of the belt should be worn low and snug on
the hips, just touching the thighs. In a crash, this
applies force to the strong pelvic bones. And you'd be
less likely to slide under the lap belt. If you slid under it,
the belt would apply force at your abdomen. This
could cause serious or even fatal injuries. The shoulder
belt should go over the shoulder and across the
chest. These parts of the body are best able to take belt
restraining forces.
The safety belt locks if there's a sudden stop or crash,
or if you pull the belt very quickly out of the retractor.
1-14

Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be
away from your face and neck, but not falling off your
shoulder.To move it down, squeeze the release lever and the
shoulder belt guide as shown and move the height
adjuster to the desired position. You can move
the adjuster up just by pushing up on the shoulder belt
guide. After you move the adjuster to where you
want it, try to move it down without squeezing the
release lever to make sure it has locked into position.

Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely to be
seriously injured if they don't wear safety belts.A pregnant woman should wear a lap-shoulder belt, and
the lap portion should be worn as low as possible,
below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't be hurt in a crash. For
pregnant women, as for anyone, the key to making
safety belts effective is wearing them properly.
Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, seeDriver Position on page 1-12.
The right front passenger's safety belt works the same
way as the driver's safety belt Ð except for one
thing. If you ever pull the shoulder portion of the belt out
all the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all
the way and start again.
